postoperative usg control and clinical follow-up of massive rotator cuff tendon ruptures

Conditions: Early Retears and Clinical Outcomes Following Surgical Repair of Massive Rotator Cuff Tears

Summary: this prospective observational study aims to investigate the tendon integrity and clinical outcomes following surgical repair of massive rotator cuff tears. patients with preoperatively diagnosed massive tears, confirmed by mri and scheduled for surgery, will be included. tendon healing will be assessed using ultrasonography at postoperative 2 weeks, 3 months, 6 months, and 12 months. clinical evaluation will be conducted using standardized scoring systems including ases, ucla shoulder score, vas, and thresholds for mcid, scb, and pass. the primary outcome is the rate and timing of retears at 12 months and their correlation with functional recovery. the study also aims to identify prognostic factors affecting tendon survivability, such as age, tear size, and muscle quality. by combining imaging and clinical parameters, this study seeks to contribute to the optimization of postoperative follow-up and rehabilitation strategies in the treatment of massive rotator cuff tears.

this prospective observational study is designed to evaluate tendon healing and functional outcomes following surgical repair of massive rotator cuff tears. the study will be conducted at the department of orthopaedics and traumatology, gazi university hospital. patients aged between 18 and 80 years, diagnosed with massive rotator cuff tears on preoperative mri and scheduled for surgical intervention, will be included. massive tears are defined as full-thickness tears involving two or more rotator cuff tendons and/or showing retraction to the level of the glenoid. exclusion criteria include irreparable tears, prior shoulder surgery on the affected side, severe glenohumeral arthritis, neurological deficits affecting shoulder function, systemic inflammatory diseases, and inability to comply with follow-up. ultrasonographic evaluations of tendon integrity will be performed postoperatively at 2 weeks, 3 months, 6 months, and 12 months. these will be conducted by a radiologist in collaboration with orthopedic residents. tendon status will be categorized as intact, partial retear, or complete retear. clinical outcomes will be measured using the american shoulder and elbow surgeons (ases) score, the ucla shoulder score, the visual analog scale (vas), and evaluated in terms of minimal clinically important difference (mcid), substantial clinical benefit (scb), and patient acceptable symptom state (pass). the primary endpoint is the rate of retear at 12 months and its association with clinical recovery. this study aims to clarify the relationship between early tendon healing and long-term functional outcomes, potentially guiding future management strategies in massive rotator cuff repair.

Eligibility criteria:
inclusion criteria: * diagnosis of a massive rotator cuff tear confirmed by preoperative magnetic resonance imaging (mri), involving at least two tendons and/or retraction to the glenoid level. scheduled for surgical rotator cuff repair at gazi university hospital, department of orthopaedics and traumatology. ability and willingness to undergo postoperative follow-up and imaging (ultrasound) at 2 weeks, 3 months, 6 months, and 12 months post-surgery. ability to provide written informed consent. no prior surgery on the affected shoulder. adequate cognitive and physical capacity to comply with postoperative rehabilitation protocols and outcome assessments. exclusion criteria: * previous surgical intervention on the affected shoulder (including rotator cuff repair, shoulder arthroplasty, or arthroscopy). irreparable rotator cuff tears determined intraoperatively (e.g., excessive retraction, poor tissue quality). presence of advanced glenohumeral osteoarthritis (e.g., hamada grade ≥ 3). neurological disorders affecting shoulder function (e.g., brachial plexopathy, stroke-related hemiparesis). systemic inflammatory or rheumatologic diseases (e.g., rheumatoid arthritis, lupus) affecting musculoskeletal function. infectious conditions of the shoulder or systemic infection at the time of surgery. inability to attend regular follow-ups or comply with the rehabilitation protocol due to psychiatric illness, cognitive impairment, or other medical conditions. refusal or inability to provide informed consent. poor general health status contraindicating surgery or anesthesia (e.g., asa iv or higher
